" `In the further disclosure of the invention had 'to the accompanying l sition to convey sounds through the horn; we, ALBERT L. MAIL- King of Great Britain, and Louis H. Cnoon, a citizen of the United:

taken on the line 8-8j1n Flg. diagrammatic showing the electrical connection for the device; and Fig. 10`is a perspective view of a modified form of cir-` cuit closing member. Referring to the views, we provide a casing 10 having the bottom lthereof open and adapted lower end of the casing 10 and adapted to engage the base 11 to lock the casing l0 on,

the sald base.

A horn 13 terminating in a reduced tubular stem 14 is adapted to be supported on a vehicle15 disclosed in Figjl and the tubuporting a horizontal L-shaped bracket 17, and the l ower end of the tubular stem 14 against the'bracket 17 and with an l,opening 19 registering with the lower end of the stem.y A tubular supporting member 20 is provided with an integral circular flange 21 abutting against the other side of the bracket 17, with the-opening to the tubular supporting member registerin` with the opening 19 in the bracket 17, suitable screws 22 being passed transversely through. the `.flange 18, the bracket 17 and the nect the lower end of thetubular stem 14to the-bracket and rigidly support the member 20,011 the bracket.-

' Aphonograph reproduce;1 .23.of any preferred type andincluding a casing 24' pI'o-f" Harige-21 to rigidly con vided With 1ateralsleeve25 and supporting a stylus ,2G-is adaptedto turn on-the supportwithout, however, having any longitudlnal movement on the'supl'aorbl lng member,and'in order to accomplish this' result, the reproducen 23 is first engaged with the supporting member 20 by having :the sleeve 25 encircleithe tubular portion of the supporting member, aftenwhich a screw 27 is lpassed transversely through a Slot 28 formed in the :sleeve 25, with fthe innerend .of ,the'screw4 extending `into 'the tubular por .tion "of the t s 4 pporting member 20,

l .thus rotatably ,supporting thereproducer 23 on `the supporting. member,` while at thesame time be adjustably cluding an armature 33 carried by a shaft 34 journaled in vertical uprights 35 secured to the base 11 and projecting upwardly on both sides ofthe free end of the brackets 31.

An end of the shaft 34 projects beyond one of the uprights 35 and keyed on the said end' toothed wheel 36 meshing of the shaft is a with a toothed wheel 37 carried on a hori- Zontal shaft 38 journaled in the upper end of the uprights 35. A drum 39 is adapted tosupported on the body of the. 37 and in order to accomplish.

toothed wheel this result a headed screw 40 is passed loosely through a central opening 41 in the drum 39 and has threaded connection with the shaft 38 carrying the toothed wheel 37, the openthe drum 39 will be loosely supported. Now

' in order to provide for an adjustment of the the adjustment of the drum to the disk-like toothed wheel 37 and shaft ldisk with-respect to the toothed wheel 37 and the shaft 38 a series of set screws 42l have. threaded connection with the drum 39 Aand pass transversely therethrough, with the inner ends of the said screws extending into recesses 43 formed in the body of the toothed'4 wheel 37. We preferably these adjusting screws 42, and it parent that in this manner employ three of will be apshown in Fig. 6, usual wave l1ne reproducer 23, against the record 45, the said spring being adapted to at all times exert an upward pull on the stylus and tend to rotate the reproducer toward the left so that'v the stylus will normally be held in engagement with the record. Now, by providing 39 with respect 38 carrying the drum, the record 45 will be supported on the drum in a'mannerlwhich. will permit of readily alining thc stylus 25 with the wave line 46 so that when the drum 39 is rotated the stylus will operate in' theare a plurality of brack` ing 41 being of a suiiciently greater diame-l ter than the diameter of the screw 40 so thatl the drum 39 can be readily adjusted so as to rotate truly with: the shaftv38. The periphery 44 of the drum 39 is preferably tapered and adapted to receive and supporta cylinder record 45, asl: the said record having the. 46 and which, in this instance, is a single continuous line extending4 entirely around the record. Now'referringv "to Figs. 2 and'3 it will be seen that the con-v tractile action of the spring 3Q holds thef pointed end of the stylus 25, carried by the:

wave line 46 of the record 45, and although the wave line on the record is very fine and a single continuous line, by providing the adjustment of the drum 39 as mentioned heretofore, it will be apparent that an adjustment of the record with respect tothe stylus can be easily obtained so that the pointed end of the stylus will operate in the wave line of the drum at all times. Rigidly carried on the other end of the horizontal shaft 38 and insulated therefrom, as shown in Fig. 3, is a circular circuit elo-sing mem# j ber 47 and rigidly secured on one of the uprights 35 and insulated therefrom is a brush 48 having the upper end thereof engaging the inner face of the circuit closing member 47, a similar brush 49 being supported on the same upright 35 and insulated from the uprightA and from the brush 48, with the upper end of the brush 49 engaging the outer. face of the circuit closing member 47. Now referring to Fig. 5 it will be seen that the circuit closing member 47 is provided with a circuit breaking member 50, which may consist of a segmental piece of mica secured to the outer face of the circuit closing member or the said member may be formed on the circuit closing member in-any other convenient manner, it being further apparent by referring to Figs. 4 and 5 that the outer brush 49 passes over the member 50 when the said member 47 is rotated.

Now referring to Figs. 1 seen that a wire 51 extends from a switch 52, in this instance carried on vthe stem 53 of a steering wheel 54 of the vehicle 15, to a binding post 55 having connection with the field of the motor 32, a second wire 56 having connection with a binding post 57 of the motor 32 and with a set of batteries 58 preferably located in any convenient place on the vehicle 15. A wire 59 connects the batteries 58 with the switch 52, and'^a wire 60 has connection with the wire 59 adjacent the batteries 58 and is arranged4 for connection with a binding post 61 of the outer brush 49, while still another wire 62 connects the wire 51 with a binding post 63 carried by the brush 48.

Y Before proceeding to adetailed description of the operation of the device, it will be understood that the wave line 46 represents, for instance, a vocal expression or reproduction of the sound of a musical instrument s0 that when the record 45 is swiftly rotated, lthe stylus 26 of the reproducer 23, operatingv -over the wave line of the record, will,

through the mediumof the .phonographic reproducer, produce a sound which will be emitted from the large end of the horn 13 and which will be an actual expression of the wave line on the record. Now when the device'is in initial position, it should be remembered that if, ,for instance, the expressionMPlease/get out of the way is used,

and 9 it will be A carrying the cyiinder yrecrnpd 45 and also ro- 'be plainlyv seen ,by1 referrin -the continued rotation of the said sitor the brush 49 will;v engage and lie Yagainst the member 50 of the. circuit closing member 47 carried on the shaft 38. Now. when itis desired. to producethe expression and havethe same emitted from the large end of the horn `13 as .a signal or alarm, the switch 52 is closed, thus completing the circuit froml the switchA to the batteries and ,the motor 32 so` that the motor will be operated and rotation imparted to the shaft 34. N ow as the shaft rotates the.`toothed wheel 36 ,will be rotated and, throu the toothed' wheel 37, wil impart rotation to the shaft 38,- ythus rotating the.` drum 39 tating the circult closing member 47. In the initial rotation. of the said member 47 ,it will gato` Fig., 5, that the member 5 0, rotating.' closing member,

member and at the faceof the circuit closing moment: that v the face anotherelectrical circuitwill be closed between the motor 32, the batteries 58 and the circuit closing-.member 47 so, that ifthe switch 52 is released, at this moment the shaft 38 w1ll continue to4 revolve in view ofthe second 4circuit being closed, as. mentioned. It will, therefore, beapparent` that the object in A Y circuits is to initially rotate the circuit clos- 'ing member 47 when the Switch 52 isfclosed, while -theprovision of lthe result in the continued rotation of v the cir` after the switch 52 second circuit will cuit closing member 47 has. been released and normally returns to an open or broken position. Now at the moment 'the circuit Ibreaking member 50 of the mem brush 49, aswell as thebrush 48, will engage circuit closing` member 47 thus resu ting inv member continued rotation of the drum 39 so that te pointed end offthe stylus 26 of the reproducer 23, operating over the wa've line of the cylinder record, will produce thedesired expression without necessitating the operator retaining .his-l hand on the switch 452. At the moment thel expressionhas been emitted from the large end of thehorn 13, and the last sound of theexpression has been completed, thedrum 39 will have made a complete revolution and in consequence thereof the circuit olosin member 47 having made a com lete revo ution, the circuit breaking memlber 50 will again be brought into engagement with kthe brush 49, -thus breaking the second electrical circuit and resulting 1n the discontinuance of the rotation and the h. the medium ofv th vwillpass beyond -,the .brush 49 so. that-the brush willengage the outer i ,brush engages. thel outer providing the two electrical ber 47 passes beyond'the brush 49, the' to rotate. I

electrical, circuit, the .circuit `breaking member 47 will continue its rotation, thus rotating the drum 39 and the cylinder lrecord 45 so that the expression will be again repeated through. the medium of the reproduoer 23 and the stylus 26 thereof, operatin over the .wave line 46 on the cylinder record?. l Therefora-each time that thefswitch 52, carried by o e steering mechanism ofthe vehicle is .closed, the expression Please get out of the or Iany other sound or expression it may be desired to reproduce 'with the particular record, te.hori1,13 to act as an alarm or signal to a .pedestrianstanding or `passing in front of ,the vehicle as it advances along the highway.

In Fig. l0 wedisclose a modified form of. circuit closing member and in which, in place o the circuit closing member 47 we provide a circularV .disk 64 similar to the on the machine described, the said disk having 'a cut away portion 65 e011-,J stituting a circuit breaking portion and adapted to perform the same function as the circuit breaking closing member 47. It will therefore be readily apparent that whether the circuit closing member 47 is employed or whether the circuit closing member disclosed in Fig. 10-is employed'in connection with the machine, each of the said circuit closing members will embody a circuit breaking portion adapted to break the second electrical circuit in order that the phono-graphic record 45 will resume a stationary position after making one complete revolution.

From the foregoing description it will therefore be seen that we provide a simple device, com act in form .and easily operable to pro uce an alarm and it should be particularly noted that in the device described neither the reproducer 23 or the drum 39 and record 45 are capable ofBJ a longitudinal movement when the device is in operation, the reproducerbeing simply adapted to turn and the drum and record By providing the adjustment of the drum described heretofore, the cylinder record can be so arranged upon the drum and with 4res ect to the point of the needle that the needle will not deviate from the wave line of the record when rotation is imparted to the record. Therefore, with a device of the character desribed it is only necessary to close the switch 52 for a momember 50 of the circuit will be emitted from lOO ment in order to produce the desired result,g this being accomplished through the medium of two electrical circuits, one of which con= stitutes an initial circuit for initially rotat-; ing the record and the other of whichconstitutes a iinal circuit for continuing thei rotation of the record to result in a complete revolution of the record so that theneedle of the reproducer will operate over theentire continuous Wave line of the record.

As mentioned heretofore, the record may be constructed Jfor the purpose of reproducing the voices of'human beings, bells, Whistles, chimes or any other sounds, which may be deemed appropriate as an alarm or signal, particularly when the device is used on,l

v vehicles such as automobiles and the like.
